目的
2
探究急性呼吸窘迫综合征(acute respiratory distress syndrome,ARDS)时机体氨基酸代谢是否异常及白细胞介素38(interleukin 38,IL-38)对T细胞受体(T cell receptor,TCR)信号激活后EL4细胞谷氨酰胺代谢调控网络酶基因表达的作用。
方法
2
募集ARDS患者及重症监护病房(intensive care unit,ICU)对照患者各3例,对其血浆进行高通量靶标代谢组学检测,筛选差异代谢物并进行通路富集分析;采用分化抗原簇(cluster of differentiation,CD)3/CD28抗体刺激EL4细胞TCR信号通路,并以IL-38干预24 h,实时荧光定量逆转录聚合酶链式反应(real-time quantitative reverse transcription polymerase chain reaction,RT-qPCR)检测谷氨酰胺代谢网络核心酶基因的信使核糖核酸(messenger ribonucleic acid,mRNA)表达水平。

结论
2
ARDS患者存在明显氨基酸代谢异常,IL-38参与调控TCR信号活化后EL4细胞的谷氨酰胺代谢。
Objective
2
To investigate the presence or absence of abnormal amino acid metabolism in acute respiratory distress syndrome(ARDS),as well as the effect of interleukin-38(IL-38) on the expression levels of enzyme genes in the glutamine metabolic network of EL4 cells after T cell receptor(TCR) signal activation.
Methods
2
Three patients with ARDS and three patients admitted to the intensive care unit were enrolled,and high-throughput targeted metabolomics analysis was performed for their plasma samples to identify differentially expressed metabolites and conduct a pathway enrichment analysis. CD3/CD28 antibodies were used to stimulate the TCR signaling pathway of EL4 cells,followed by IL-38 intervention for 24 hours,and RT-qPCR was used to measure the mRNA expression levels of core enzyme genes in the glutamine metabolic network.
Results
2
In the ARDS group,nine metabolites were upregulated in plasma,i.e.,2-oxophenylalanine,5-hydroxylysine,mevalonic acid,2-hydroxybutyric acid,L-cystine,L-phenylalanine,3-methyl-2-oxovaleric acid,L-valine,and isoleucine. Compared with the control group,the IL-38 intervention group had significant increases in the relative mRNA expression levels of solute carrier family 1 member 5,glutamine synthetase,glutamate dehydrogenase 1,glutathione reductase,glutamate-cysteine ligase modifier subunit,glutathione synthetase,isocitrate dehydrogenase 1,glutathione peroxidase 1,glutathione peroxidase 4,and ten-eleven translocation 1(
P
<
0.05).
Conclusion
2
Significant abnormalities in amino acid metabolism are observed in ARDS patients,and IL-38 participates in the regulation of glutamine metabolism in EL4 cells after TCR signal activation.
